This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

它能够抑制自身免疫病的发生和发展，参与肿瘤免疫的调节，同时在感染和移植免疫中也发挥着极其重要的作用。T细胞的这一亚群具有免疫调节和免疫抑制的特性，新近发现它亦与爱滋病的发生、发展关系密切HIV进入人体后，CD4D25调节性T细胞抑制了机体的免疫效应但它也同时被感染，最终由于细胞毒的作用而死亡由于调节性T细胞数量的减少不能有效的发挥其抑制作用，HIV持续的过度活化使得T细胞逐渐耗竭说明在HIV发生、发展的不同阶段Treg细胞可能都发挥了免疫抑制作用，但是却对HIV感染与爱滋病发病的进程产生了不同的效应。

By the study of the relationship between vegetation and spatial characteristics of UHI, the mainly spatial characteristics of UHI has been analyzed and it was:(1) The terrain of the suburbs is higher than the urban region, the gradient of the terrain height is small, and this geomorphological featrue is conducive to assemble of the heat, the UHI phenomenon of Changsha is obvious especially in the summer night;(2) The UHI distribution is similar to the outline of the urban construction. The LST of urban is 3-5℃ higher than the flat low areas close around the city, and 6-8℃ higher than further areas. The region which has the most obvious UHI phenomenon is the region surrounded by the second city ring road, and the UHI phenomenon gradually weakened from the city centre to suburb;(3) The impact of geomorphological character to UHI is notable, the relationship between vegetation index and UHI is Anti-related, it was indicated that the improvement of the vegetational status is very important to the elimination of UHI phenomenon, the implementation of the urban green land planning can reduce UHI effect.

通过分析长沙城市地区的土地覆盖、植被绿地状况与热岛空间分布状况的关系，揭示出研究区域UHI主要特征为：(1)从研究区域地表覆盖图发现，长沙市城区四周均有相对地势较高的山地，但地形梯度不大，接近四面环山的地貌特征，容易造成城区的热量聚集，有利于城市热岛效应的形成，使得长沙城区存在明显的热岛分布；(2)UHI分布与城市结构的轮廓相一致，长沙城区与地势相对平坦的近郊区的地表温度差异为3~5℃，与地势较高的周边远郊区的地表温度差异为6~8℃，长沙城区热岛效应与城市规划呈对应关系，热岛效应最显著的区域为二环线内，并从中心沿三环逐渐向郊区减弱；(3)地表覆盖类型对UHI的效应明显，长沙地区植被绿地状况与UHI呈现明显反相关分布，揭示出植被绿地对降低UHI具有重要的作用，大范围的绿地建设能有效降低UHI。

The value that can be provided to an organization can be enhanced or diminished by the review that an auditor conducts of the organization's response to a nonconformity, as well as by the "close-out" process that is applied.

审核员发现不符合，开出不符合报告后，如何对待被审核方针对不符合报告所采取的行动加以评审，以及关闭所开出的不符合报告，通过这样的行动可以帮助组织提高价值，也有可能降低价值。

The appearance of the front cylinder is enhanced by the positioning of the starter motor close to its base, and by tapering the chrome-plated push rod covers, the visual impact of the huge V-twin engine is heightened.

外观前线缸是提高定位的起动机电机接近其基地，并放缓了镀铬推杆涵盖，视觉冲击力的庞大的V型双引擎提高。

The rebounding damping technology, that the function in the same kinds of products sold in the market are not in common, means when you pull the drawer out to the bottom, it will has a process of soft closing and rebound, which can reduce the noise made by the things loaded in the drawer in efficiency. Moreover, because of the variable damping technology, which help to lessen the force of of the inertia made by the motion of the box when open or close it, and it will extend the useful life of the cabinet effectively. Therefore, it proved that the two-way slow motion cabinet have a longer useful life than the single soft-closing drawer system. And that is the reason why GRASS HOPPER is so popular in many countries all over the world.

反弹阻尼技术就是当你的橱柜抽屉拉到尽头时，有一个轻微的缓冲反弹过程，这样就减小了抽屉里面的装载物的碰撞声音，能达到更加实际意义上的静音，同时由于具备这种功能，在开合抽屉时就大大减小了由于抽屉的运动惯性对柜体产生的破坏力，这样就有效的延长了橱柜的使用寿命；所以使用双缓冲抽屉的橱柜比使用单缓冲抽屉的橱柜寿命明显延长，而市场上还没有具备这种功能的同类产品。
